中文摘要: 针对风廓线雷达估算的反射率数据需要进行验证，开展雨滴谱仪与风廓线雷达反射率对比试验，通过两种不同探测设备观测数据的对比，以验证风廓线反射率数据的可靠性和可用性。结果表明：确定了以风廓线低模360~1440 m采样体积内的反射率与3 min雨滴谱反射率数据对比方法能最大程度的减少时空差异；在雨滴谱仪反射率小于40 dBz时，对应的风廓线雷达反射率数据是可靠和可用的；同时由于风廓线雷达有限的动态范围造成反射率低估的现象，使得风廓线雷达反射率在大气垂直结构以及微物理特性等方面应用受到一定的局限性。

Abstract:Focusing on the need that the reflectivity data estimated by wind profile radar should be validated comparison experiment of the reflectivities of wind profile radar (WPR) and the raindrop disdrometer was carried out. Through the comparison of the detection data from the two kinds of detection equipments the reliability and usability of the wind profiler radar reflectivity is tested. The results show that the contrast method between the reflectivity of the low mode 360-1440 m of the wind profile radar and the reflectivity of 3 min raindrop disdrometer is determined to reduce the temporal and spatial differences in maximum extent. When the raindrop disdrometer reflectivity is less than 40 dBz, the wind profile radar reflectivity data are reliable and available. At the same time, the limited dynamic range of the wind profile radar causes the phenomenon of underestimated reflectivity so that the application of the wind profile radar reflectivity is limited somewhat in the atmospheric vertical structure and microphysical properties and so on.
